Mixed mode is slower than G mode?even with N adapter?

So...I have a laptop with G, a desktop with N and a wired computer...

1.When I set the router to G mode, the wireless computers(laptop with G, a desktop with N) copy files from the wired computer is around 2-3 MB/s

2.When I set the router to N mode, the wireless N desktop copy files form the wired computer is around 8MB/s. And my wireless G laptop is not able to connect to the router.

3. When I set the router to mixed mode, the bad thing happen.
a. Sometimes the N desktop is 4MB/s, and the G laptop is 3MB/s
b. Most of the time both of the wireless computers are getting 500KB/s

So..I just wonder why the mixed mode is sooo unstable.
Answer from linksys:
Yes, Mixed Mode is slower than "Wireless G only" or "Wireless N only". There are multiple wireless devices/clients that would share the connection on "Mixed Mode". Whereas, wireless G only or "Wireless N only" it limits to Wireless G and wireless N clients respectively.


I am using linksys 300N router.
The question is...why do we need mixed mode??G mode is even faster!
Why buy a wireless N router?
Isn't most of the wireless N adapters are compatible with G and B?
Or I just don't know how to setup the router?

Any other router has a better mixed mode?So I can get 7MB/s+ for the N wireless, 2MB/s+ for the G wireless at the same time.
Maybe I have to get a dual band router?
Also, Is there any laptop support dual band wireless?(without any adapter)

Thanks!

 

Then change your laptop wireless G card to N. Even if it's internal, most likely it can be swapped to N one for something around $20. You'll get faster transfer speed of all your wireless and wired computers.

Changing your wireless router to dual band wireless N currently will cost you $100 to $200 or could be more for certain models.

 

You should always use Mixed mode only when using network devices of different wireless protocols. N or G only is only to be used when all devices are of one type. That's what Mixed is for - when you have devices of different wireless standards. But you need to find the right settings and balance.

Make sure your NAT setting and UPnP settings are also Enabled, and that you've entered a unique SSID for your Router. If you haven't, it's easy to connect to a neigboring network using the default Linksys SSID as well - your system doesn't know the difference.

You're only considering your Router - in order to get optimum throughput you need to setup your ADAPTER settings also to match your Router's setting. Most people only consider the Router, never that the adapter must be setup as well.

Also, your Router Port setup can be changed to give you better throughput as well. If you open your Router Admin Panel and go to the Applications and Gaming link, you'll see the panel for QoS - Quality of Service. Using QoS allows you to set your system up to have Priority Access to the Router at all times. If you don't, any other signal going through the Router can bump you down the priority list for access.

Port Forwarding is as important for applications as well as gaming. Encryped Security will also slow your speed down - consider using MAC Address filtering instead, unless you're a CPA or doing a lot of online transactions.

Getting a DBN Router won't help you unless you change all your adapters to DBN also, something people don't realize. Without DBN adapters you can't get the full potential of a DBN network. Is it worth it? Damn right it is, is you have the requirements for speed and access. If not it may not be worth the cost.

Other elements to consider for speed:

UNDERSTANDING THROUGHPUT
SYSTEM RESOURCES
WHOLE NETWORK FRAGMENTATION

To access most adapter settings, you can access them through the Wireless Network settings window in Vista, or via the Device Manager. In the Dev Manager, right click on the adapter and click on Properties. You'll see the Settings tab. Go through and setup the adapter to match your router settings.

On your particular Router, go to the Linksys site, download the current firmware revision, and save it to your system. Go to the Administration area of your Admin Panel. Save your current configuration (Backup) then follow the instructions to flash the firmware with the update. If the revision matches the one you have, do it anyway - this is standard Linksys Support Procedure when anyone has a speed/signal problem. Once the flash is complete, Restore your configuration.

You might consider getting an external USB adapter also - even though I have n Intel 4965agn, I also use a WUSB600N to use with my WRT600N Dual-Band. the Intel won't access the Dual-Band features of the Router, and I use the 5ghz band for my business and gaming data streams. The USB tends to get higher throughput speeds than the Intel anyway.

The 2 attached PDF's include specific setup information for a Linksys Single Band and Dual-Band N Router. I used to have a 300N - the Admin Panel is the same as the 600N, except for the 5ghz Band. The first one has Adapter setups for an Intel and WUSB600N Adapter - by looking at them and comparing them to the Router setup, you'll get an idea of how to setup your own.

The second attachment has much more detailed settings for the Router - it includes all specific settings, including examples of Port Range Forwarding and Quality of Service settings, as well as MAC Address Filtering setup.

Between the links and the attachments you should be able to get a better understanding of how your Router should be setup to match your Adapter. The 2nd attachment also has other information on other aspects of Network speed and signal strength not commonly found.

The procedure were written for a post I did for the Playstation Network on Router/PS3 setups, so if you see any PS3 references, that's why. A PS3 has a Wireless G adapter, so it's a good reference for your G device. I bypass my PS3's G adapter with a DBN Adapter so I can get N throughput when I'm gaming.

PM me or click on my WA Super link in my sig to send me an email if you have specific questions. Remember also that Linksys will bend over backward to help their hardware users, but you need to register your hardware on their site first or they won't deal with you.
